Operating System As A User/Computer Interface:
A modern computer system consists of one or more processors, memory(primary and secondary), clocks, terminals, disks, network interfaces and other input/output devices. All in a complex system. Writing programs that keep track of all these components and use them correctly is an extremely difficult job. So, a layer of software is put on top of the bare hardware, to manage all parts of the system, and present the user with an interface or virtual machine that is easier to understand and program. This layer of software is the operating system.
